Not much gets past a dog"s nose. They have about 50 times more olfactory receptors than we do, helping make their sense of smell up to 100,000 times stronger. But what about those soulful eyes?
没有什么东西能逃过狗的鼻子。他们的嗅觉受体比我们多50倍，使得他们的嗅觉比我们强10万倍。但他们那深情的眼睛呢？
Here are a few examples to reveal the world as our best friends see it.
这里给大家几个例子，揭示我们的好朋友“狗”是如何看这个世界的。
Since dogs can"t see red, they perform similarly to humans who are red-green colorblind. Dog visionis blurrier, since they have four to eight times less visual acuity. Dogs lose sight of patterns from 20 feet away that most humans could see from 75 feet. 由于狗看不到红色，所以它们的视觉与人类的红绿色盲很像。而且狗视力模糊，它们的视力敏锐度比人类低4-8倍。狗从20英尺远处就已经看不到大多数人能从75英尺看到的图案。 Fur color might help dogs recognize each other from a distance, along with related signals like body size and shape. The reddish coat may seem green to other dogs, still it helps them distinguish the differences between each other down the street — at least until they get close enough for a propersniff-down. 毛皮颜色可能有助于狗从远处识别彼此，如身体的大小和形状。图中的红毛，在其他狗看起来可能是绿色的，但这仍然可以帮助它们 |
